I studied the Polar support pages and according to them the application requires Android version 4.3 or higher - Is that the reason for the failing installation?

What about in the future is our Alien-Dalvik virtual engine be able to provide support for higher android versions than now?

Is the Android version issue also related to the Linux kernel that we currently have in SF OS? Will the coming kernel update help Jolla phone to accept and run android apps higher than it can support know?
